Can u plz help me answer question 30

slamgirl [31]

We are given:

$3x^3-2x^2$

There seems to be nothing I can do to simplify this equation. However, I can factor out an $x^2$ since they both have at least an $x^2$ . Here is what we get:

$x^2(3x-2)$

This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.
